COMET U0111 – 1-Channel Temperature Data Logger for 1 External Pt1000 Probe

The external Pt1000 input measures temperature from ‑90 to +260 °C (±0.2 °C from ‑50 to +100 °C, ±0.2% of reading above that, ±0.4% from ‑90 to ‑50 °C). The acoustic and optical alarm (buzzer + LED) immediately warns when adjustable threshold limits are exceeded. Min/Max values are stored. The backlit LCD display offers excellent readability; measurement/alarm update rate is adjustable (1 s, 10 s, 1 min). The logger runs independently on a 3.6 V AA lithium battery – lifetime several years depending on interval. No power supply required – ideal for fixed or mobile installations. Recording modes: non‑cyclic (stops when memory full) or cyclic (overwrites oldest data). Real‑time clock with date/time. Data transfer via USB‑C to PC (COMET Vision Software).

The datalogger is maintenance‑free, long‑term stable and comes with a 3‑year warranty. The included traceable calibration certificate ensures highest measurement accuracy from the factory. Intuitive operation via buttons and clear menu. The compact housing (61 × 93 × 32 mm, approx. 130 g incl. battery) with IP67 protection makes it resistant to dust and splashing water. Whether used as an autonomous logger in production, a mobile tester in service, or a fixed element of a monitoring chain – the U0111 impresses with precision, robustness and user‑friendly operation. The Pt1000 probe (available separately) allows measurements in pipes, ducts or confined spaces.
